Applying a client policy to a group of channels

ABSTRACT

Management and provisioning of networking traffic may be provided by bundling virtual channels into a group. A global policy may be applied to the bundle so that virtual ports providing services to a client may be managed by referring to the global policy of the bundle. The channels comprising the bundle may span multiple physical ports and in some cases, multiple physical switches. Thus, policy management may be avoided at the port level and instead, be handled as groups of channels implementing a client service.

RELATED APPLICATIONS

The present continuation application claims the benefit of priority of U.S. application Ser. No. 13/741,982, filed Jan. 15, 2013, which application is incorporated herein by reference in its entirety.

BACKGROUND

The present invention relates to network management, and more specifically, to a applying a client policy to a group of channels.

Network traffic going through a physical port may be controlled or monitored via properties that are applied to the physical port itself. Furthermore, an 802.1Qbg standard may define how virtual ports may be created and how to apply policies on each of the individual virtual ports. Under the IEEE 802.1Qbg standard, one or more “S-Channels” may be created and each channel may be associated with a profile ID. A server can have multiple virtual machines (VMs), where a network administrator can set up the policy (or a profile ID) for a given VM in a network database. When the VM is registered with a switch, the switch can query the network database to get one or more fields of the specified profile ID and map at least one field to the VM.

A problem may arise when certain services for a given client or a customer are to be offered based on (or using) an aggregate group of these S-Channels or virtual ports that can span different physical ports. For example, a given customer may require (or may be required to have) certain policies regarding services or restrictions (e.g. per customer's service level agreement (SLA)) to be applied to all of the customer's channels. These types of policies may not be put in the profile ID because the profile ID may be applicable to multiple customers and the channel may need customer specific configuration(s). Thus, a challenge is presented in how to standardize maintaining operating properties for each channel or virtual port profile and/or access control lists (ACLs) while complying with the properties for the aggregate bundle or group of channels.

DETAILED DESCRIPTION

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics may include:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed, automatically, without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Cloud Software as a Service (SaaS): the capability provided to the consumer may be to use the provider's applications running on cloud infrastructure. The applications may be accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer need not necessarily manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Resource pooling: the provider's computing resources may be pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources, but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities may be rapidly and elastically provisioned, in some cases automatically to quickly scale out, and may be rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or process, or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module,” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable media having computer readable program code embodied thereon.

Referring now to FIG. 1, a schematic of an example of a cloud computing node 10 is shown. The cloud computing node 10 illustrated is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, the cloud computing node 10 is capable of being implemented and/or performing any of the functionality set forth hereinabove.

In the cloud computing node 10 there is a computer system/server 12, which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with the computer system/server 12 include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, handheld or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like.

The computer system/server 12 may be described in the general context of computer system executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. The computer system/server 12 may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

As shown in FIG. 1, a computer system/server 12 in the cloud computing node 10 is shown in the form of a general-purpose computing device. The components of the computer system/server 12 may include, but are not limited to, one or more processors or processing units 16, a system memory 28, and a bus 18 that couples various system components including the system memory 28 to the processor 16.

The bus 18 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.

The computer system/server 12 may typically include a variety of computer system readable media. Such media could be chosen from any available media that is accessible by computer system/server 12, including volatile and non-volatile media, removable and non-removable media.

The system memory 28 could include one or more computer system readable media in the form of volatile memory, such as a random access memory (RAM) 30 and/or a cache memory 32. The computer system/server 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, a storage system 34 can be provided for reading from and writing to a non-removable, non-volatile magnetic media device typically called a “hard drive” (not shown). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media could be provided. In such instances, each can be connected to the bus 18 by one or more data media interfaces. As will be further depicted and described below, the system memory 28 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.

A program/utility 40, having a set (at least one) of program modules 42, may be stored in the system memory 28 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. The program modules 42 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.

The computer system/server 12 may also communicate with one or more external devices 14 such as a keyboard, a pointing device, a display 24, etc.; one or more devices that enable a user to interact with the computer system/server 12; and/or any devices (e.g., network card, modem, etc.) that enable the computer system/server 12 to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 22. Alternatively, the computer system/server 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via a network adapter 20. As depicted, the network adapter 20 may communicate with the other components of computer system/server 12 via the bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with the computer system/server 12. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.

Referring now to FIG. 2, an illustrative cloud computing environment 50 is depicted. As shown, the cloud computing environment 50 comprises one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, a personal digital assistant (PDA) or a cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or a automobile computer system 54N, may communicate. The nodes 10 may communicate with one another. They may be grouped physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud the computing environment 50 to offer infrastructure, platforms, and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 2 are intended to be illustrative only and that the computing nodes 10 and the cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 3, a set of functional abstraction layers provided by the cloud computing environment 50 (FIG. 2) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 3 are intended to be illustrative only and embodiments of the invention are not limited thereto.

Examples of workloads and functions which may be provided from this layer include: mapping and navigation; software development and lifecycle management; virtual classroom education delivery; data analytics processing; transaction processing; and network channel bundling.

In general, embodiments of the present invention may provide a method of applying a given policy to a group of channels. One more services may be offered on a bundle or a group of virtual ports, where any one of the virtual ports can be associated with any one of an existing group of physical ports. A server and switch combination may be aggregators across different physical ports, and/or different physical servers, where any one of the offered services may comprise one or more fields, wherein at least one of the fields may be replicated and applied across all the specified channels within the defined group of channels or virtual ports.

Referring now to FIG. 4, a network system 100 (referred to sometimes as system 100) is shown according to an exemplary embodiment of the present invention. The system 100 may include a data center server 110 in communication with a network switch 120 in a multi-channel environment via a plurality of channels 135. The data center server 110 may include a plurality of data sources, for example edge relays 115 ₀, 115 ₁, 115 ₂, 115 ₃ to 115 _(n), (referred to collectively as relays 115). Two physical ports 125 (labeled as “A” and “B”) may connect the data center server 110 to the network switch 120. Physical connections between the data center server 110 and the network switch 120 may be provided by Ethernet connections 160. For sake of illustration only, the channels 135: “1A” and “2A” are defined as part of physical port 125 “A”, and channels 135: “1B”, “2B” and “3A” are defined as part of physical port 125 “B”. In this example, both ports 125: “A” and “B” are physically located within the same network switch 120. Software may configure the network switch 120 to include a plurality of virtual ports 145 residing within the network switch 120.

The channels 135 may be virtual channels established or created to provide a connection between a VM running on the data center server 110 and one or more of the virtual ports 145 on the network switch 120. Each channel 135 may be created within either port 125 (“A” or “B”). A group of channels 135 or virtual ports 145 may be defined per client as a bundle 170, 180. In some embodiments, the channels 135 may be S-channel types. Client specified properties may be applied or shared between all of the channels 135 of the bundle 170, 180.

A bundle 170, 180 may span multiple physical ports 125. For example, a bundle 170, 180 may be defined to receive a first client (or service type or customer) set of properties. Each property may include one or more field values. An exemplary set of properties may be seen in table 105. Bundle 170 may comprise three specified channels 135, for example, those labeled as “1A”, “2A”, and “1B” that span both physical ports 125 “A” and “B”. Similarly, channels 135 labeled as “3A” and “2B” may be grouped together as bundle 180 and may be defined to receive a second client (or service type or customer) set of properties. Bundle 180 may also span both physical ports 125: “A” and “B”.

In some embodiments, all the traffic going via a single channel 135 may be tagged according to the channel designation, for example, “channel 1A”. The receiving entity may determine, using the channel's tag, that it is Ch. 1A, and may apply the policies pre-specified for channel 1A traffic. There may various types of properties (for example those in table 105) which may be defined as part of the channel's profile.

In an exemplary embodiment, a group of virtual channels 135 (for example, bundles 170, 180) may be established where a given client or group policy may possess or share different service types or profiles. The group of virtual channels 135 may comprise one or more virtual channels that may have common or similar characteristics but do not necessarily have the same profile or correspond to the same server or switch as the other channels.

For example, as shown in FIG. 5, a system 200 is shown, similar to system 100 except that the data center server 110 may be connected to multiple network switches 220 and 285. The network switch 220 may include the physical port 125 “A”. The network switch 285 may include the physical port 125 “B” and a third physical port 125 “C”. Furthermore, channels “1A” and “2A” may be defined as part of physical port 125 “A”. Channel 135 “2B” may be defined as part of physical port 125 “B”. Channels 135 “1C” and “1B” may be defined as part of physical port 125 “C”.

A bundle 270 of channels 135 may be defined to receive another client (or service type or customer) set of properties. Bundle 270 may comprise three channels 135: “1A”, “2A”, and “1C” that may span both physical ports 125: “A” and “C”. Channels 135: “1B” and “2B” may be grouped into a bundle 280, which may defined to receive a fourth client (or service type or customer) set of properties. In exemplary embodiments of the present invention, channels 135 may be grouped together into a global group, where all the channels 135 may be defined across and spanning multiple switches (for example, switches 220 and 280) or servers.

In an exemplary embodiment, the specified channels within the bundle 270 may comprise virtual channels 135 of different types of network traffic. Each virtual channel 135 may be defined by a profile. Each profile may include an individual profile identification (ID) and policy parameters defining a policy usable on the channel. Profile IDs may be mapped to each channel 135 which may be provided to the switch 220 or 280 corresponding to the channel 135. The switch 220 or 280 may look up the profile ID in a table and may set the policies applicable to the channel 135 based on the information in the table. For example, channel 135 “1A” and channel 135 “2A” may be defined to have a storage traffic profile. Storage traffic services may need guaranteed end to end reliability and thus a lossless traffic policy may be applied to the traffic of channels “1A” and “2A”. Channel 135 “1C” may be defined to possess a web server profile, and thus a specific web traffic policy may be applied to channel “1C”. For example, a client may want to prioritize bandwidth usage across channels 135 using a bandwidth policy. The bandwidth policy may include SLA's applied to queues of the virtual ports 245 to obtain the necessary bandwidth.

By applying an overall client policy to a bundle 270, 280, the grouping of multiple channels 135 may be realized when all three channels 135, for example channels “1A”, “2A”, and “1C” belong to the same client or customer. When employing a client's SLA, client policies specific to that client may be applied to all of the client's channels. In some embodiments, the properties of such a customer's policy may not necessarily be implemented or used in the profile ID of each individual virtual channel because the profile ID may span to different customers and also may have various generic shared properties with other channels located associated with the same physical port 125. Thus, in an exemplary embodiment, a client's policy may be generated using the client's SLA and then the client's policy may be applied to or matched to a bundle 280 that spans any of the channels 135 used by a client. This may be beneficial for example in a dynamic environment when a server transfers a virtual machine to another server.

Referring now to FIG. 6, a method 300 of applying a customer's policy to a group of channels 135 is shown according to an exemplary embodiment of the present invention. An operating system may establish (310) a plurality of virtual ports and channels to the ports on a switch(es). The operating system may group (315) a plurality of channels into bundles. The operating system may use hardware assisted support to apply (325) a local policy to all physical ports on a switch that correspond to channels within the bundle. The hardware assist function may keep track of all ports within a physical hardware platform. For example, if bandwidth metering is desired for all traffic for a given customer, in accordance with the customer's SLA, then a hardware assisted “metering bucket” may be dynamically realized that may track a customer's traffic across multiple physical ports within the same switch or server. However, if the bundle spans multiple switches or servers, then the hardware assist function may require additional coordination and synchronization between the various hardware platforms to maintain or apply (330) a global policy to the bundle. The operating system may use software to aggregate (335) data from various switch elements (e.g., switches/servers/ports/channels) to apply a local or global group policy to the bundle. The software may be a master process that retrieves data from various locally running processes. The master process may aggregate the data per local or global group properties. Higher layer/level network services may also be used to apply (340) a policy on bundles of channels that are pertinent to the rest of the network (i.e. core router, ISP, DHCP server, etc.).
